WGCShop is now accepting pre-orders of the Magpul PTS PMAG which are expected to be released late August. The PMAG™ (Polymer MAGazine) is a lightweight 120 magazine for the M16. This PMAG™ features a straight body and hopefully uses also a stainless steel spring  and a pop-off storage/dust cover that alleviates pressure from the magazine feed lips like in the PMAG magazine for the real steel guns.
